When electrodes deviate from their planned path, the error isn’t random. It’s a consistent, reproducible systematic error — which means it can be corrected once recognized.

Our new paper in Operative Neurosurgery (e-pub ahead of print) shows that both cannula and non-cannula approaches are subject to the same deviations. The real driver appears to be brain tissue mechanics, not the surgical tools.

Although correction is possible, the real challenge ahead is moving from reactive fixes to proactive strategies that prevent bending before it occurs. That’s not easy — but it’s where the field needs to go.

Stroke recovery shouldn’t stop before you’re ready!

The RESTORE study — led nationally by Dr. André Machado and Cleveland Clinic — is testing whether brain stimulation ( ) can help survivors regain use of their arm and hand.

We are honored to bring this groundbreaking research to patients here in the Delaware Valley, with Thomas Jefferson University and Jefferson Health serving as one of the national study sites.

CNN recently featured this important work: https://amp.cnn.com/cnn/2023/08/14/health/deep-brain-stimulation-stroke

If you or a loved one in our region is living with arm weakness after a stroke, you may qualify. Learn more: http://restorestrokestudy.com/jefferson
